It has been years since the Chinese get plastic bags from supermarkets for free. China has banned
free plastic bags at shops and supermarkets, but people have to pay for them. The Chinese once used
about 300 million of plastic shopping bags a day, which has caused environmentally pollution because
plastic bags are not easy to break down. So the Chinese is encouraged to take their own bags for
shopping. Then what kind of shopping bag is the best to carry? Some student in Chongqing have a
extraordinary idea. They use old clothes to make cloth bags, and then to ask their parents and friends
to use these cloth bags instead of plastic ones. They do so because they think it is our duty to help
protecting the environment.
